Methodology
Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
13 of the 27 named sources that could be read published a usable figure; 14 published none and are recorded as not published, never filled in; 2 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in GBP (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 25 figures, never sentences; 268 candidate sentence(s) were refused by a reviewer with the reason recorded.
The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per SKU per merchant: the pack price, the pack size, the coverage the manufacturer states, and the price per square metre those three give.
What nobody publishes: the SAME-SKU SPREAD across merchants (a 25kg K Rend silicone top coat read at one merchant against another on the same day), the price per square metre of a whole SYSTEM built up layer by layer (adhesive, board, basecoat, mesh, primer, topcoat, beads) rather than by the bag, and the share of the installed rate in the price index above that the materials actually account for - which is the number that tells a homeowner whether a quote is labour-heavy or material-heavy.
Retail against trade price where a merchant publishes both.
268 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
